Abstract
A process is described for isomerizing pentenenitrile in a reactant stream, wherein the isomerization is effected over a heterogeneous catalyst in a distillation column in such a way that, during the isomerization of the isomerization reactant, it is distillatively depleted in relation to the isomerization product in the reaction column of the distillation column.
Claims12
A process for isomerizing pentenenitrile in a reaction stream, wherein the isomerization takes place over at least one heterogeneous catalyst, selected from the group of the oxides of main group 3 or 4 or of the oxides of transition group 3 or 4 of the Periodic Table of the Elements, in a distillation column at least comprising a bottom zone, a reaction zone and a top zone, and, during the isomerization, the isomerization reactant is distillatively enriched in the reaction zone of the distillation column in relation to the isomerization product.
